A permalink is the permanent web address of a single page or post - like yoursite.com/about. Good permalinks are short, readable, and stay put, which helps both visitors and Google.
Also known as: URL slug, pretty permalink, post URL
In plain English
A permalink is the full web address of a page or post - the part after your domain. WordPress can generate them automatically, and you can edit the "slug" portion to make them short and readable (yoursite.com/emergency-plumbing instead of yoursite.com/?p=1234).
Why it matters for your business
Readable permalinks help both visitors (they can guess what a link contains) and Google (keywords in URLs are a minor ranking signal). Changing permalink structure after launch breaks every existing link unless you set up redirects - a common SEO mistake.
When you'll run into it
When creating content (you can edit the slug before publishing), and critically when changing site structure - always redirect old URLs to new ones.
